LUBRICATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 232,097, datedSeptember 7, 1880,

Application filed July 21, 1880.

To all whom it may concern Be it known that I, CHARLES W. WOOD- FORD, ofEssex, in the county of Essex and State of New York, have inventedcertain new and useful Improvements in Lubricating Apparatus; and I dohereby declare that the following is a full, clear, and exactdescription of the same.

My invention relates particularly to that class of lubricating devicesin which the lnbri' cant is contained in a chamber and thrown off bycentrifugal action, and is intended to be used principally in connectionwith the forg ing-rollers of nail-machines, its special design being,while doing away with the webbing or other absorbent packing nowrequired, to easily and efficiently control the flow of the lubricant.

The apparatus may be briefly described as follows: Within the stockcarrying the roller is formed a chamber, into which the oil or otherlubricant is introduced. This chamber communicates by a smallcylindrical passage with a side chamber, whence the lubricant passes bya duct to the bearing-surface.

In the head of the, stock, and exactly opposite to the narrow passagebetween the chamhers, is formed a threaded opening, in which works asetscrew having a needle or taper point, which is at any desired partnearly or quite the diameter of the passage connecting the two chambers,so that by advancing or retracting the setscrew this needle-point isdriven more or less into the passage, wholly or partially closing it,and thus regulating or stopping the flow of the lubricant.

For full comprehension, however, of myinvention, reference must be hadto the annexed drawing, the figure showing a sectional elevation of theapparatus applied to the forgingroller, 850., of a nail-machine.

Similar letters of reference indicate like parts.

A is the stock proper, A being the head in (N0 model.)

which is carried the roller B, revolving on spindle b.

C is a chamber formed in the stock A, into which the oil or otherlubricant is introduced through an opening, 0, which may be closed inany desired way; and D is a cylindrical passage, preferably of smalldiameter, from the chamber 0 to the secondary chamber E, E being thepassage from this to the bearingsurface.

F is a screw, threaded into acorresponding opening formed in thestock-head A and axially in the same line as the passage D, into whichthe tapered or needle end f enters, this being at any desired point ofthe same diameter as the passage.

F is the head of the screw, of any shape which will enable it to beturned easily, and G a jam-nut, which may be used to secure it in thedesired position. It will be seen that by turning this screw F itsneedle end fentcrs a greater or less distance into the passage D, eitherclosing it entirely or leaving but-a small space through which thelubricant can pass, or it may at will be withdrawn therefrom altogether,thus allowing full flow.

I am aware that lubricating devices embracing a central chamber and sidechambers filled with packing adjustably compressed, communicatingtherewith and with the surfaces to be lubricated, have already beenpatented, and therefore do not claim such, broadly.

What 1 claim is as follows:

In a lubricating device, the combination of an, oil-chamber andsecondary chamber with duct to bearing-surface, connected together by apassage in which is moved adjustably the taper or needle end of aset-screw carried in the holder, all substantially as set forth, and forthe purposes described.
